Add an option to prevent HTML from being generated

[ericjim]

In my current project, I am only relying on the outputted json file to generate documentation. Is there any way to prevent HTML from being generated? I do not use those files. This is somewhat related to #257

You should be able to do this by calling the generateJson method on an Application instance.

It would be something along the lines of

const src = Path.join(__dirname, 'src');
const out = Path.join(__dirname, 'docs.json');
const app = new TypeDoc.Application({
  mode: 'modules',
  out: 'docs',
  theme: 'minimal',
  tsconfig: './tsconfig.json',
});
app.generateJson(app.expandInputFiles([src]), out)

My initial reaction is that this doesn't need to be part of the CLI so I'll close the issue.
